Oil Viscosity; How To Read Oil Container Labels; Api Service Symbol; Ilsac Certification Mark - Subaru 2014 BRZ Owner's Manual

Oil viscosity (0W-20 is explained here as an example):
•• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
•• The 20 in 0W-20 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.

How to read oil container labels:

Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
